In the mechanism shown, the block B is constrained to move vertically and is attached to the bar BD. The point A on the bar AD is fixed. Express all your answers in the component system shown.
At the instant shown, bar AD is rotating counterclockwise with angular speed ωAD = 30rad/s, which is decreasing at 4rad/s2, ϕ = 45°, and θ = 30°. If ℓ = 24 cm and d = 16 cm, determine the acceleration of the block B at this instant.
